DETERMINATION OF IMPURITIES IN TITANIUM AND TITANIUM DIOXIDE BY NEUTRON ACTIVATION ANALYSIS .I. SIMULTANEOUS DETERMINATION OF 16 TRACE ELEMENTS IN TITANIUM

The most important metallic impurities in titanium which give long-lived isotopes on neutron irradiation can be determined by a rapid anion-exchanged seperation of Ti, Sc, Cr, Na and Ag, after which the resin, containing most of the impurities, is counted on a high-resolution Ge(Li) γ-spectrometer. Cu, W, As, Ga, Au, Sn, Fe, Zn, Co, Ta, Mo and Ni can be determined in one measurement, while Na, Cr and Ag can be determined after an additional separation from the Sc isotopes, the major activities originating from the titanium on neutron irradiation. Three different samples were analysed five times, and the reproducibility of the results was good. © 1968.
